摘要： An image forming apparatus includes an operating section, a control section and an image display unit. The operating section accepts inputting operations for settings on information on an image forming size of an original image and a setting on a paper sheet size. The control section compares the image forming size with the paper sheet size, and outputs, if the image forming size exceeds the paper sheet size at least in either of a lengthwise direction and a lateral direction, a notice signal to cause a notice to that effect. The image display unit displays a preview image based on the notice signal.

摘要： An image forming apparatus for performing image formation on a fed sheet includes a feeding unit, a detecting unit, a conveying control unit, and a first, second, and third determining unit. The feeding unit feeds a sheet of an irregular size onto a conveyance path. The detecting unit detects timings at which a leading edge and trailing edge of the fed sheet pass through a conveyance path predetermined position. The first determining unit determines a length of the sheet in a width direction. The conveying control unit discharges the sheet to a discharge destination without performing image formation on the sheet. The second determining unit determines a length of the sheet in the conveyance direction. The third determining unit determines a sheet size of the sheet of the irregular size from the length of the sheet in the width direction and the length of the sheet in the conveyance direction.

摘要： An image forming apparatus includes a plurality of removable developing units each of which has an image carrier whose width is narrower than a width of a printable area of the printing paper, and a driving unit for driving the plurality of the removable developing units. The plurality of the removable developing units are disposed in different rows parallel to a main scanning direction such that one end of an image producing area of an image carrier of a first developing unit coincides with one end of an image producing area of an image carrier of a second developing unit adjoining to the first developing unit. The image forming apparatus further includes a control unit for supplying printing data to the plurality of the removable developing units in timings shifted form row to row.

摘要： The image forming apparatus includes an original document size detector device for detecting a size of an original document to be processed and a non-standard size input instruction screen 34 for inputting a size of an original document to be processed. Normally, the original document size detector device detects a size of an original document, and original document image data is processed based on the obtained original document size information to reproduce an image on paper of a corresponding size. The non-standard size input instruction screen 34 is provided with a an X key 46 and a Y key 47 that enable the operator to, when inputting thee size of the original document, select and input new original document size information using an incremental key 44 or a decremental key 45 after reference values are provided based on original document size information obtained by the original document size detector device. The image forming apparatus can be thus offered with improved operability in manual input of the size of the original document or recording material.
